Mavenir held its annual analyst event this week and highlighted some important information highlighting its progress in transitioning to a maturing ecosystem player in the telecom equipment industry.  The company highlighted its recent Koch Brothers $500M investment; existing investors include Intel/Nvidia and Siris Capital, who remain majority equity holders.  The company highlighted that it grew revenues and bookings in the mid 20’s percent year-over-year in its Fiscal 2020, an impressive figure.  Two main themes came from the show.  First, the company’s RAN portfolio is picking up steam.  Second, the company’s portfolio now spans very wide, from telecom core to RAN.
 
The RAN portfolio has made significant progress.  The company claims over 20 deployments in 14 countries.  And, Mavenir has demonstrated the capability to deploy on AWS, IBM Cloud, Microsoft Azure, Oracle Cloud, Google Cloud, and VMWare.  The company spent a great deal of time reviewing definitions of various Open RAN terminology, to address confusion, spanning from vRAN, O-RAN, C-RAN, Cloud-RAN, and Open vRAN.  We’ve seen many public statements from Mavenir, its competitors, operators and pundits, alike, espousing the various benefits of some or all of these systems.  We think the point Mavenir was making at its conference is that Open vRAN is the most open, interoperable system.  When operators enable open systems, of course, it allows Mavenir and other vendors to bid on deals for networks that have existing equipment from traditional vendors like Ericsson, Nokia, Huawei, and ZTE.  We see Mavenir’s efforts to work with various infrastructure companies and systems like AWS and VMWare as a means of gaining a foothold with operators who are trialing or in the early stages of deploying these various infrastructure systems.  Speaking of partners, the company claims it has relationships with nearly 15 Remote Radio Unit (RRU) players.  The company says it can deliver Massive MIMO capabilities to customers, which means that its RAN systems can satisfy what would be considered mainstream 5G use-cases; this represents very significant progress over last year’s RAN capabilities. 
 
Mavenir’s portfolio is extensive.  The company made separate presentations about the following topics: RAN, OSS, Radio, Packet Core, Mobile Core, BSS/Digital Enablement, Security, Private Networks, and Enterprise over three days.  With over 5,000 employees spanning the globe, exposure to the most relevant parts of the mobile infrastructure industry, Mavenir is a serious contender for deals.  The company also highlighted that its telecom core technology uses modern programming techniques that enable it to operate on cloud infrastructure; among these are fully containerized micro-services design.  The company shared that most microservices file sizes are under 25 Mbytes, evidence that the systems are designed as microservices (and can load fast). 
 
The fact that in April 2021, well-known Koch Bros made a $500M “strategic minority” equity investment in the company is an important validation of Mavenir’s place in the telecommunications industry.  We see the investment as a reinforcement of the company’s balance sheet and an opening to new customers. 

This week's MWC Barcelona 2021 had several themes; the most important was that several outsiders to the telecom industry were ever-present.  The new entrants – the party-crashers - included Starlink, Microsoft Azure, Amazon Web Services, Google Compute, and NVidia.  These new players are forcing change either through economics, new technology, or new regulatory frameworks, or combinations thereof.  We’ll touch on the importance of these crashers and then circle back to a few other ongoing themes that continue to remain relevant in this article.

Satellite broadband, while not exactly a mobile technology, will catalyze significant changes to the mobile industry.  Low Earth Orbit (LEO) satellite services, evangelized today by SpaceX-owned Starlink, announced plans to spend as much as $30B in building out its constellation over its lifespan. Yet, it will reach users across the globe.  Elon Musk said Starlink is in beta in 12 countries, and it plans to have ½-million users in the next 12 months.  The billionaire highlighted that Starlink’s ability to reach rural populations is unlike that of terrestrial players.  We think the rural reach of LEO broadband is precisely why Starlink will be so important.  Musk’s pitch to the mobile industry was that of a partnership – he said that Starlink is partnering with 5G MNOs to offer satellite backhaul and rural broadband services.  We view satellite broadband, and later 3GPP satellite, as critical components in the telecommunications industry, and therefore we chose to write about satellite first in this article.

All three hyperscalers, Azure, AWS, and GCP, made a splash at MWC21.  As a group, these infrastructure providers have already changed the way telcos operate.  In fact, the hyperscalers’ architectures were the inspiration behind the decade-old telco push for Network Functions Virtualization (NFV).  But, these days, hyperscalers’ operations are more than an inspiration to the telcos.  MNOs are now moving some of their workloads to hyperscaler infrastructures.  The evolution of these workload migrations to hyperscalers is moving in three phases, phase 1, the back-office, then phase 2, telecom core, and last, phase 3, the access layer. In the weeks leading up to MWC21, we’ve seen progress on all three workload migrations, including that on Mobile RAN.  Incoming AWS CEO Adam Selipsky said at MWC that AWS is talking to “virtually every telecom operator.” 

​Some examples of announcements made surrounding the MWC show include:

• Phase 1: AWS / Verizon various relationships, AWS / Netcracker (NEC) relationship
• Phase 2: AT&T is moving 5G/4G core to Azure (inside of AT&T facilities)
• Phase 3: GCP / Ericsson relationship

With Open RAN capabilities come the possibility that MNOs can source various RAN components from multiple vendors.  Rakuten has already technically demonstrated multi-vendor sourcing (Altiostar baseband and Nokia and NEC radios).  In addition to system-level multi-vendor interoperability, in previous years, multiple semiconductor companies had been bolstering their RAN offerings (Marvell, Qualcomm, EdgeQ).  Marvell had previously crashed MWC (MWC19 and MWC20) and is now a RAN supplier to Samsung and Nokia.  For MWC21, we saw yet another entrant to the RAN chip market, NVidia.  NVidia has received pubic endorsements from Ericsson, Fujitsu, Mavenir, and Radisys.  NVidia’s current chip offering is called “AI-on-5G,” and the company’s offering starts in 2021 as an “on a server.” NVidia’s next offering is expected in the 2022-2023 era and will be an “on a card” offering.  Then, after 2024, NVidia will offer its “on a chip” offering.  

Ericsson Capital Markets Day Part Two:

Networks summary:  When asked how it took market share (North American has 53% share 2Q20, up 5% vs 2018), management pointed to having made more significant R&D investments in radio than competitors. It cited Dynamic spectrum Sharing and its cost-efficient radio-related ASICs as examples of valuable features to customers.  
The company expects O-RAN will continue to evolve, with limited uptake starting in 2023.  Cited IPR challenges as one challenge.  Elsewhere in the presentation, it said it is #1 contributor to 5G standards; we take it that this IPR gives Ericsson leverage to slow ‘O-RAN’ down.

Digital Services:
The team said the split of Digital services for T4Q 3Q20 as (excluding IPR, consulting, and learning services):
•    BSS 20%
•    OSS 25%
•    Comm services 15%
•    Packet core 20%
•    Cloud and NFV infra 10%
The Digital Services team has:
•    addressed 37 of the 45 ‘critical and non-strategic’ projects
•    revised its BSS strategy, and it is now 5G focused
•    75% of its portfolio exposed to growth as of 3Q20 sales
•    Cloud infrastructure has 200 customers
•    5G Cloud core has 80 customers (includes “5G” EPC and 5GC SA contracts).  Packet core should grow faster than the others
•    5G SA count is now at 30.  5G SA revenues should begin in 2021 from most of these contracts.
•    BSS has 120 contracts, 9 of which were competitor swap-outs
•    Orchestration has 100 customers
Dig Services software + support in T4Q 3Q20 was about 55% of total revenues, and it expects 60% by 2022.  It has about 40% recurring revenue T4Q 3Q20 and expects it to be about 55% by 2022.  Expects Japanese and Korean operators to deploy SA by the end of 2021; expects Japanese 5G market to ramp very soon because it is a heavy user of iPhones.  It expects 600K 5G base stations in China in 2020 and the same number in 2021.  
Emerging Markets Summary:
Recently acquired Cradlepoint has > 60% GM and a recurring revenue SaaS model.  200K enterprises, 3,000 public agencies, 1,500 channel partners.  It has won 30 dedicated network deals.

Ericsson has served the mobile service provider industry well over the years.  Most devices connected to its customers’ networks are mobile phones; this, however, is changing.  Internet of Things (IoT) devices are entering the fray and provide an avenue for growth, as is the enterprise market.  Additionally, Ericsson’s channels have mostly been to operators, at a time when enterprise growth is expected to provide additional cellular industry growth.  Ericsson’s portfolio, until the Cradlepoint acquisition, was not particularly well-positioned to benefit from IoT and enterprise growth vectors. 
 
IoT devices come in all shapes and sizes, and they use a number of different connectivity methods, from cellular to Wi-Fi to Bluetooth to LoRa and many others.  In 2020, we expect only 16% of IoT and wirelessly connected devices will connect to cellular systems; the rest connect to more popular (and mostly free) connectivity types.   We see cellular connections growing in the future, but as a percentage of all IoT and wirelessly connected devices, we expect it will drop to 13% of all such devices five years from now.  The reduction in the fraction of IoT and wireless devices connected to cellular is why the “cellular to other” gateway market (Cradlepoint’s main market) makes sense.  There are some use cases where cellular backhaul connections to connect Wi-Fi, Bluetooth, Zigbee and others are vital.
 
With US-based CBRS and European nations’ private enterprise spectrum opening up the opportunity that enterprises will build their own networks – without needing a mobile operator’s help with sub-leasing licensed spectrum – the folks at Ericsson had a choice to make.  The choice was to continue selling to and through mobile operators and hope that mobile operators keep their share of enterprise and IoT growth, or to acquire products and distribution channels to access enterprise growth. 
 
Ericsson’s competitors were partnering with Cradlepoint with some success.  Recently, Nokia’s enterprise revenues hit about 10% of revenues, in part because it was selling LTE gear to customers in verticals such as utilities, mining & exploration, and logistics & shipping.  Many of these customers were using devices such as Cradlepoint’s.  Ericsson is now invited to these ongoing dialogues as these networks expand and change.
 
We would be remiss if we didn’t mention 5G in relation to Cradlepoint.  Some enterprises seek a secondary wireless connection to supplement their primary wired broadband connection.  Gear such as Cradlepoint routers can serve this need well.  In this sense, we can see why Ericsson uses messages such as “Ericsson accelerates 5G for Enterprise with the Cradlepoint acquisition.” 
 
This acquisition is not without controversy, in our view.  The Swedes are acquiring a company located in Boise, Idaho, and as such, managing from afar may present challenges.  Cradlepoint sells its devices differently (mainly through channels) from how Ericsson sells its gear (mainly direct); these two distribution methods may conflict.  Ericsson sold its cell phone business many years ago because it conflicted with its mobile infrastructure business.  Similarly, Cradlepoint gear is focused mainly on enterprises, we see a similar conflict because Cradlepoint’s customer base liked its independence from cellular gear-makers.  If Ericsson can manage through these challenges, it may enjoy exposure to IoT, enterprise and 5G gateway growth opportunities.

Before the consolidation in the Mobile Radio Access Network (MRAN) market that occurred in the past decade during Huawei’s ascendancy, there were a dozen major RAN vendors.  They included Motorola, Lucent, Alcatel, Siemens, Nokia, Ericsson, NEC, Fujitsu, Samsung, Nortel, Huawei and ZTE, and they hailed from the US, France, Germany, Finland, Sweden, Japan, Korea, Canada and China. 


As Huawei entered the market, using a price aggressor strategy, it catalyzed mergers, resulting in the elimination of Motorola, Lucent, Alcatel, Siemens, Nortel, plus a reinforcement that led to the Japanese and Korean players to sell primarily to their home markets.  The result is that in many markets during recent years, there were only two vendors left, and that left operators with little choice but to look elsewhere. 

The punchline is that going forward, due in part to Open RAN, and in part to the response of operators looking outside their traditional supplier base, we now have 10 RAN players who can bid on projects.  And there is a multiplier on top of the 10 players, because going forward,  operators can buy radio heads from different vendors than their primary RAN baseband vendor, essentially doubling the number of choices an operator has when making mobile RAN vendor decisions.

Here is how we arrive at the conclusion that there were only two players per major geography.  Just a couple years ago, the state of affairs was quite different; we had only Nokia, Ericsson, Huawei and ZTE as players, and last year, it became clear that in the US, only two major players were left.  In China, the same could be said, with Huawei and ZTE as main suppliers (Ericsson has won business there and Nokia ceded the market in 2019).  And in 2020, we’ve seen much of Europe and English-speaking Asia whittle down to two suppliers, as well.

And here is how the procurement teams at operators have much choice in the future.  The “Open RAN” vendors are now deemed viable given the success at Rakuten and the push by operators to demand Open RAN compliance, and these include Altiostar, Mavenir and Parallel Wireless.  Nokia and Ericsson are invited to most, if not all bids worldwide. 

Huawei and ZTE are invited to many, but a declining number of bids in markets that are siding with the US viewpoint.  We saw a turning point in late 2018 when AT&T announced it will buy from Samsung, who has now gotten a strong foothold in both India and the US.  And, more recently, we have seen two Japanese players, NEC and Fujitsu, in some way filling in the void left by Huawei and ZTE’s woes in the US/China spat, as they get wins (Fujitsu recently won DISH) and get invited to bid (NEC and Fujitsu are being asked to bid on UK projects).  Add these up and we have Altiostar, Mavenir, Parallel Wireless, Nokia, Ericsson, Huawei, ZTE, Samsung, NEC, Fujitsu. 

There are other factors at work that are adding to more RAN choices, as well.  Two such trends are Facebook’s efforts, ONF’s efforts and the variety of radio head vendors who are now viable with Open RAN/FB/ONF efforts.  Facebook has promoted projects such as Telecom Infra Project (TIP) that have many goals, including one that supports the goal of $1,000 radio heads (these cost much more from the major vendors). 

The Open Network Foundation (ONF) supports projects such as SD-RAN and Aether. 
Radios can be purchased from non-traditional sources, as well because with all three projects we have mentioned above (TIP, ONF SD-RAN and Open RAN), these allow radio purchases to be made separately from baseband purchases, literally doubling the choices that operators have when building out a roster of vendors.

The trends in mobile RAN have changed significantly.  Vendors with little to lose (startups and players entering new markets) are getting aggressive to grow their businesses.  Incumbent vendors are at risk, as their business practice of selling baseband and radio simultaneously to captive operators is coming to an end.  We may look back at this early 5G era and say there was a lot more to it than just the upgrade to 5G, and it begs the question, who will acquire whom to consolidate the market once again and get pricing under control.

ORAN and CBRS were the main themes at Mobile World Congress Americas, held in Los Angeles. I have to say, though, that unlicensed was the third most important theme, though it will emerge to the main stage in future years.

ORAN encompasses several topics woven together. ORAN is a set of common interfaces that describe how various devices in mobile RAN work together. ORAN may also represent a new way of building radio networks. Recently, new vendors are being invited to bid on major mobile network projects, including Mavenir, Altiostar, Parallel and others. And, the major market share players in mobile RAN, which include Ericsson, Nokia, Huawei, Samsung, and ZTE are being asked by operators to support ORAN. The incumbent vendors are responding in various ways: Samsung, a challenger in the market, has whole-heartedly embraced ORAN, while Huawei has only recently acknowledged the existence of ORAN. Ericsson and Nokia have embraced ORAN with the view to embrace and extend - in the sense that Microsoft used this term in the 1990s. Based on presentations made by Ericsson, Nokia, and Samsung, we expect that the incumbents, Ericsson and Nokia,will embrace ORAN but will establish a path to continue serving customers with the same vertically integrated business models of today. We are eager to see the results of mobile network operator bidding to observe how many startups win projects for wide scale deployment.
 
CBRS. Today, CBRS is available in the US market and has been so for about a month. We had an interesting opportunity to moderate three panels on the stage at MWCa and found some very interesting indoor/campus uses for CBRS, including WiFi backhaul, secure/critical communications, surveillance, IoT/sensor monitoring. Since CBRS indoor spectrum generally allows for more output power than for WiFi, the range is better. We see this as a key advantage for CBRS users, though enterprises who take advantage of the so-called OnGo service must pay various monthly fees such as those for the SAS and potentially other ongoing services. We expect that CBRS will be successful in certain verticals.
​
Unlicensed.  We believe the existence of CBRS could uncork the value of unlicensed spectrum at 900 MHz, 5 GHz, 2.4 GHz, and 6 GHz. We are conducting significant research into each of these and other spectrums.

​We attended the operator and vendor consortium of 5G Americas.  The themes of the show were: 5G, spectrum, cell siting, Asia-Pacific operator progress.  For the second time in the past couple weeks, we saw FCC Commissioner Michael O'Reilly present, and his key messages were similar both times, focusing on CBRS, C-Band and 6 GHz.  In attendance from the North American service provider side were AT&T, T-Mobile US, Shaw, and Sprint (we focused on NA operators mainly in this write-up).  Notable vendors included Cisco, Commscope, Ericsson, Intel, Kathrein, Mavenir, Nokia, Qualcomm, and Samsung.  We would say the most important theme from the show is the surge in interest in unlicensed spectrum, both for the use of mobile operators, as well as competing carriers, as well as by enterprises both for indoor and outdoor applications.  For this write-up, we are focusing primarily on comments made by some of the leading operators who attended the conference.

AT&T discussed mmWave, future 3GPP releases, 5G phones, Mobile Edge Computing and indoor cellular, mid-band spectrum strategies, 5 GHz spectrum usage, Mobile Edge Computing (MEC), StandAlone (SA), among other topics.  AT&T views mmWave as just a tool in the toolkit, so to speak, and not the only spectrum that is useful in 5G.  It considers mmWave to be most helpful in urban and potentially indoor settings.  Representatives said that future 5G-oriented Releases 16 & 17 are expected to be software upgrades to existing hardware and won't require new equipment to incorporate these new capabilities which will include network slicing.  AT&T is making a big deal about its Mobile Edge Computing (MEC) initiative.  At the conference, it emphasized MEC as having two main parts: a) expansion to about 100 edge sites (mostly Central Offices) from about 20 central locations in the LTE era and initially supporting packet core, and b) Microsoft Azure services managed end-to-end by AT&t.  The company also emphasized that it plans to pursue some indoor cellular opportunities, some that currently leverage 5 GHz using LAA technology, some that will leverage CBRS and some that will leverage mmWave.  We get the impression from AT&T that it is open in how it pursues future mid-band spectrum strategies.  Its strategy could change based on: a) the timing of the CBRS PAL licenses (currently slated for June 25, 2020), b) the potential for C-Band  private auctions (potentially in the mid 2020 timeframe), c) the potential for some or all of the 6 GHz spectrum availability (where Wi-Fi 6 would co-occupy), as well as other factors.  We learned that, at least in certain regions, the company is making very ample use of 5 GHz spectrum using LAA techniques.  AT&T seeing its picocells (small cells) get around 100 Mbps from LAA out of a total 130 Mbps inclusive of around three other licensed spectrums.  We were surprised the company makes such ample use of unlicensed spectrum where Wi-Fi currently exists.  The 5 GHz experience of AT&T leads us to think that 6 GHz, which promises to offer far more spectrum that the 5 GHz swath presently available, could be very beneficial to mobile operators and their consumers, as well as the Wi-Fi industry, and its consumers.  AT&T expects that by this time next year, it will be "pushing" 5G to all its customers, part as a result of handsets adopting 5G capabilities, part the result of its network seeing nationwide coverage.  Of the services that AT&T operates, it is installing mainly Packet Core in its MEC systems.  AT&T is also planning to run Microsoft Azure services in its MEC locations.   It expects that both Packet Core and Azure will see a 10-20 ms latency reduction by being located in MEC locations.  AT&T says that StandAlone (SA) is "just new software," and downplayed the significance of the upgrade from EPC/NonStandAlone (NSA) to SA.

Sprint "is all-in on 2.5 GHz mid-band deployments for 5G services."  Given the company's potential merger with T-Mobile USA, we view its network-build-out choices as being somewhat limited.  It has limited options because it increases its near-term value to its acquirer, T-Mobile, if it deploys 5G in 2.5 GHz.  Likewise, it is doesn't implement in mmWave, this reduces overlap with T-Mobile, who is deploying there.  The company reiterated that it had launched 5G in 9 markets.  It is seeing its peak speeds on 5G (aided by the fact that it has simultaneously upgraded hardware to Massive MIMO) be about 3-5 times that of its 8T8R LTE systems.  It currently covers 11M POPs and 2,100 square miles with 5G.  Sprint also shared that it sees RFPs from customers to replace Wi-Fi with 5G, though it didn't share more about this topic.  The company's experience is that in upgrading its macro base stations to Massive MIMO 64T64R capabilities, it is getting 3-4x faster throughput than its 8T8R systems, though in the field these measurements vary widely.  Additionally, Sprint said that its Massive MIMO systems relative to earlier systems show "generally the same coverage," with 1-2 dB better sometimes.  Sprint is exploring ORAN and vRAN but "not adopting near term."

Shaw (Canada) presented its mobile LTE and 5G efforts and plans.  Shaws plans are interesting because the company has significant cable services deployed in Canada.  The company said nearly all the mobile technology it has installed in the past three years are "5G-ready."  It will use 5G first in 600 MHz, then in mid-band (probably in 3.5 GHz) and the last in mmWave. Shaw expects that low-band 5G handsets will be available in 2020, and, similar to what AT&T said, it expects that is when 5G mobile will start in earnest in Canada.  Shaw admitted that it is behind where the US operators are in deploying 5G, but offered no apologies, as it felt it is where it needs to be from a competitive standpoint in Canada.  Almost laughing, Shaw explained that it would never consider deploying mmWave along highways, and that only high-density locations would get mmWave coverage.  Shaw's view that mmWave is for high-density locations was shared universally by other operators in attendance, including AT&T, Sprint and T-Mobile US.

T-Mobile US spokespersons explained that mmWave has seen some challenges, relative to initial expectations and that while it does get mmWave to operate beyond near-line-of-sight, the view of T-Mobile is that mmWave is "just part of 5G."  T-Mobile expects 3GPP Release 16 to be completed in 2020, but that it will be 2021 before it deploys Release 16, which won't require "a massive hardware refresh" and which will incorporate industrial and connected vehicles features.  T-Mobile views 5G as being appropriate for indoor installations because while mmWave has challenges penetrating glass and concrete, but when 5G operates in low and mid-band spectrums, the "issue goes away."  By 2020, T-Mobile expects StandAlone packet core to be ready, but since its current EPC/NonStandAlone (NSA) systems are already virtualized, the upgrade to SA is "not a forklift" upgrade.  T-Mobile says virtual RAN (vRAN) "will take time," and that it will "need accelerators," which we take to mean FPGA-based Network Interface Cards (NICs) or the like to allow servers to operate faster than just x86 processors will allow.

​We attended the CBRS Alliance event in Washington DC today, and by our rough estimate, about 350-400 people were in attendance representing groups such as regulators, legislators, lawyers, technology vendors, property owners, service providers, investors, media and analysts.  We were impressed with the widespread interest in the new shared spectrum technology and services running in the 3.5 GHz band that is now called “OnGo.”  We have researched CBRS for many years and found several acronyms and CBRS-specific terminology to be blossoming.  We found several themes at the CBRS Alliance event and a follow-on event at Federated Wireless, a SAS service provider, of special note: a) the OnGo experience will serve as a mold for regulators, operators and other interested parties not just in the US, but also the rest of the world, b) Tier 1 operators and WISPs appear focused on Fixed Wireless Access (FWA) deployments in CBRS spectrum, at least initially, c) many presenters focused on the “OnGo backhaul to gateways” use-case, at least as an initial opportunity, d) interested parties have a concern that PAL licenses may become very expensive when the auctions occur, and e) there were a very large number of devices supporting OnGo at this event.

Acronym soup.  The CBRS Alliance did its best to explain the various acronyms and how the various players work together.  It would take at least six pages to cover just the top-level details.  The idea here is that the 150 MHz of spectrum in the 3.5 GHz range was previously used exclusively by the US Department of Defense and is now going to be shared using a three-tier process, where the military (the incumbent) will have use of it when it needs, then private license holders will get next dibs (PAL), followed by general users (GAA).  Starting today, GAA users will begin use of the spectrum in the Initial Commercial Deployment (ICD) that was announced today, starting at 9 AM Eastern.  A group of service providers called Spectrum Access System (SAS) providers have been authorized to install radios on the US coastline that sense when the military is using the spectrum and send channel-use information to equipment that is operating in the CBRS spectrum.  These SAS providers will, therefore, coordinate the frequencies between incumbent, PAL, and GAA users.
​
Our view on why OnGo and “Shared spectrum” matters.  We expect that by sharing spectrum amongst various parties, more traffic can move across a smaller range of frequency than by using the more common method of auctioning off frequency bands to be used exclusively by one entity.  We estimate that shared frequency will carry ten-times more traffic than frequency bands licensed for the exclusive use of single entities.  Thus, it is for the greater good that this OnGo / CBRS experience go the distance and allow a public demonstration of whether multi-tiered shared spectrum can succeed or not.  Already, we have the experience of shared spectrum in the 2.4 GHz and 5 GHz bands used by WiFi – there is no doubt this has been successful; in fact, most public estimates show about 80% of smartphone traffic is carried by WiFi rather than cellular systems, all of which as of yesterday was carried on licensed spectrum.  At the CBRS Alliance event, guest speaker, US FCC Commissioner Michael P. O’Reilly said that based on the success of OnGo, he expects similar models could be applied to additional spectrum (and he implied this might the sequential order of launch): C-band (3.7-4.2 GHz), 3.45-3.55 GHz, 3.1-3.45 GHz and 7 GHz (which we understand is meant to be the same thing as what is being discussed at 6 GHz by the WiFi community).

FWA opportunity is front and center.  Charter and AT&T focused their comments on their plans to deploy fixed broadband systems.  AT&T shared some impressive statistics about the performance of recent trials using Massive MIMO cell sites using distributed RAN over CBRS spectrum, which is connected to indoor baseband over fiber optics to the radio sites and then connects wirelessly to customer premises equipment mounted at the roofline: it said it achieved 140x12 Mbps at slightly over one mile over line of sight using 20 Mhz channels. Charter discussed it had deployed its first commercial FWA in Davidson City, NC to rural locations.  It also discussed how it uses dual SIM systems to allow customer coverage to Verizon’s cellular network. Charter also discussed private LTE, neutral host, and Industrial IoT use cases.  The Wireless Internet Service Provider’s Association (WISPA) President spoke about its members’ enthusiasm for OnGo and explained that 100’s of WISPs used the 3.65 GHz spectrum and expects more will use the 3.5 GHz / CBRS spectrum.  Currently, WISPA says WISPS in the US have 6 million customers.

OnGo as a backhaul.  We detected a theme that seems durable: CBRS spectrum can be used by enterprises with far-flung operations to save costs by reducing the installation of wired / optical cables and associated infrastructure.  There was an impressive list of vendors who had equipment at the show, a number of which were gateway devices that made connections between CBRS and other well-known protocols such as Ethernet and WiFi, to name a couple.  While OnGo/CBRS support is not as widespread on devices today, IoT devices supporting other wired and wireless systems certainly are, the list of which includes WiFi, Zigbee, Bluetooth, Ethernet and more.  We were taken by how compelling some presenters made a case for using CBRS simply assuming a reduction in new cabling to enable new systems such as kiosks, surveillance, digital signage, farming, and so on.  Many of these examples would increase the deployment of existing protocols like WiFi, Zigbee, Bluetooth, and Ethernet, instead of reducing their demand.  The idea that OnGo/CBRS competes with existing systems may be incorrect.

PAL auctions.  Commissioner O’Reilly said PAL auctions are scheduled for June 25, 2020.  In our formal and informal interviews, we understand there is a growing concern that CBRS spectrum auctions could be aggressively pursued not only by existing Tier 1 mobile operators but also by other players, not least of which could include MSOs and maybe even “Big Tech” companies.  Since the 3.5 GHz spectrum is where many countries besides the US have begun deploying 5G services, making equipment in these frequency bands commonplace, there is ample reason to want to use this spectrum in the US.  Bidders may raise the price high enough that enterprises will choose not to compete, and won’t view the CBRS spectrum as attractive as they had hoped.  In this case, PAL would look quite a bit more like a typical licensed spectrum, similar to other auctions.

OnGo devices abound.  At the show, the following vendors had devices on show (see pictures):  Sercomm, MultiTech, Sierra WIreless, Zyxel, Encore, Cradlepoint, AMIT Wireless, Commscope / Ruckus, Accelleran, Bai Cells, Cambium, Samsung, Google, LG Electronics, Sequans, Telit, JMA Wireless, Motorola Solutions, Cisco, BEC Technologies, Ericsson, ip access, BLINQ, Comba Telecom, and Westell.

Huawei hosted 700 analysts and media participants in Shenzhen China last week to attend its annual analyst summit, nick-named HAS2019.  The company's high-level message was simple - the company is an innovator and is moving down the stack into semiconductors and is partnering with and funding university projects to develop basic research.  This year’s message was different from than the prior-year meeting, but several transformative events have occurred between this meeting and the prior year's, most notably the 2Q18 shipment ban on ZTE, the US / China trade dispute and US efforts to thwart Huawei’s participation in the 5G infrastructure of its allies.  Interestingly, during HAS2019, the Apple and Qualcomm announced their chip-supply and patent settlement, Samsung announced its foldable phone (which has been met with criticism), and Ericsson & Swisscom announced that the operator went live with its 5G network.  All three of non-Huawei events highlighted the importance of Huawei’s chips and innovation announcements.

The company made announcements in its main keynote presentations on day one about seven different chip projects delivered recently or planned shortly.  Chip-level is unusual for what are typically high-level presentations from a keynote-level presentation.  These chips (seen in accompanying pictures) are:

• Ascend 310/910.  Artificial Intelligence (AI) chip for cloud (leads to its Data Center Ethernet Switch iLossLess cloud service)
• OptiXtreme H6 oDSP.  Optical transmission Digital Signal Processor (DSP).
• Hi 1822.  FC/IP chip used for products including Solid State Drives (SSDs)
• Atlas 200 AI acceleration for AI computing intended for September 2019 announcements at Huawei Connect
• Tiangang 5G Basestation chipset
• Balong chip series intended for 5G smartphones and other Customer Premises Equipment (CPE)
• Kungpeng ARM chips for computing

The company shared more details about other chips in breakout sessions on the second and third days of the conference, as well.  The point we are making, though, is that upper-level management provided significant detail about semiconductor developments at Huawei.

The company shared more details about other chips in breakout sessions on the second and third days of the conference, as well.  The point we are making, though, is that upper-level management provided significant detail about semiconductor developments at Huawei.  Another relevant semiconductor-related point to make is that the company is de-emphasizing its reliance on Intel-based architecture and instead is focusing on devices such as ARM-based processors, as well as GPU, FPGA and NPU semiconductors.
We would be remiss if we did not mention some of the system-level announcements and observations related to 5G that were made at the HAS2019 conference, which include:

• MU-MIMO.  Of Huawei’s 70,000 shipments of 5G base stations as of the show, 97% were MU-MIMO based.  The company expects MU-MIMO to be deployed not only in urban areas but also in rural areas.
• SingleRAN Pro.  The company is taking an architectural approach that is different from what some service providers in the world want; it is delivering an integrated product approach where multiple frequencies and base stations are integrated into the same enclosures.  This converged approach is different from the architectural approach being promoted by some smaller vendors like Altiostar, Mavenir and Parallel Wireless, which uses the O-RAN standard and features a disaggregation between various components like antenna and base band processing.  Huawei’s rationale is that it is less expensive on capital spending and operational spending to use the integrated approach.
• Converged Mobile Packet Core.  The company plans to have 1H19 commercial availability of its 2G/3G/4G/5G NSA/5G SA packet core system.  In slides depicting this product, it prominently features chip systems such as GPU, FPGA, NPU, and ARM but specifically excludes x86 references. 
• Huawei expects to deliver its first 5G phone in November 2019

Mid-band spectrum shortages in the US was the main thrust of the 5G Americas sponsors. The idea is that the rest of the world has lots of mid-band spectrum available and service providers in countries that could be considered economic leaders (Japan, Korea, China, Western European countries) have plenty of available mid-band spectrum that is ideal for 5G, while the US does not.  This group at 5G Americas, which includes service providers, vendors and standards bodies, is saying that US leadership in cellular infrastructure and the entire app economy that relies upon it may be at risk as 5G get deployed.

Other topics discussed:  AT&T is currently out for bid on its 5GC infrastructure, and this caused some interesting posturing by the vendor attendees (like Ericsson, Nokia, Cisco, Mavenir) at this conference, with each trying to identifying their strengths.  It seems the consensus is that all mobile operators in the US market are using Option 3X, an EPC anchoring system.  And, the consensus seems to be that US operators will need to move to 5GC once most traffic is coming over 5G Radio (“New Radio”).  Vendor selection appears an open field, once again, as 5GC has 13 different microservices, each which could theoretically be parsed out to different vendors.  Operators are saying, though, that while this multi-vendor selection may lead to savings on purchasing, it will increase integration spending, so these two have to be balanced out. 

Mobile Edge Computing:  The consensus is that a 50 mile radius (or others are saying 100 km) is considered the ‘edge,’ or the ‘low latency’ zone.  We expect, however, that the data forwarding plane (‘user plane’) will be distributed to, say, 100 locations within a territory like the US market, while the control plane will be much more centralized (perhaps as centralized as it is currently, where it might be considered to be like 1/4th the number of locations). 
​
CBRS.  The consensus is that testing will be done by mid November 2018 and Initial Commercial Deployment by 1Q19, potentially spilling into 2Q19.  PAL auctions are expected by attendees to be a 2019 event, with 2020 traffic running on PAL spectrum. Commscope represented the views from a SAS standpoint for this discussion.There were discussions about the C-Band (6 Ghz) potentially using the same type of Automatic Frequency Coordination system, but the consensus is that it is too early to declare that the path forward.
